All of a sudden my mac powerbook stopped making sound? is there a key combination to fix it. It's like it has been muted, but the mute button doesn't change anything.

You got to open this thing up and make sure the speaker connections are on tight and clean all the dirt and lint around the speakers and connections. If that don't work then you have to replace the speakers or the sound/power board.

It sounds like your sound is muted (SONIDA MUDA). Hopefully you can understand these instructions in english. My espanol es limitado.
SEGUNDO: SOUND then turn on internal speakers.
If that does not work, try spraying compressed air into the EARPHONE JACK. This will reset it back to internal. Sometimes small objects get stuck in the earphone jack and trick the computer into thinking that you have earphones plugged in all the time. I hope this helps you!

I have no sound from my built in speakers or from my headphones, my volume was working properly earlier but stopped suddenly. I've checked the audio MIDI and nothing is muted but I still have no sound.

All right people have a bunch of really short solutions to these problems that aren't really solutions on this site. They just seem to be like yo somethings wrong with your computer. It might be your firmware. Well try this... Zap the PRAM

1. Shut Down.
2. Start up and hold cmd + opt. + p + r
3. While holding this the computer should start up and
automatically restart your computer again while still holding it.

Upon the second start it should Make a Chime and the sound should come back. If not then its not your firmware. It Might be that you threw away your built in speaker prefs. or the speaker shorted and u need a new one. To test this plug in your headphones to see if they work. If not then you have an internal software problem and you should take it to a technician. He may have to reload your system so back everything up. And be ready with the Mac start up discs that were given with the computer. Hope this helps. I'm going through the same thing right now with my G4 and am at the point where I need a tech. I may just buy a new Comp. (I love my G4 though)

My Verbatim suddenly stopped working on my Mac OS

It sounds like your hard drive is damaged. Hard drives are very, very dilicate pieces of machinary. The disk is paper thin and any sudden jarring, especially dropping it creates a warp in the drive. It could also be just a mechanical failure. Unplug it to prevent further damage. Don't worry in many cases you can have the data retrieved from your hard drive by using this online company that I highly recommend:

I need Help!! Plz Help Me!!!

The phones are probably not reaching the bottom of the connection where the MP3 is told to stop sending sound to the speaker.

Test with other phones.

If the problem persists, a firmware update would be a good idea.

I have no sound on my HP Pavillion laptop

I had the same problem, but now its solved!

Brieftly speaking, my internal speaker stopped producing sound, but when I plug earphones in, there is sound in the earphones.

Just plug in-and-out ur earphones several times (it took me 5 tries) and voila internal speakers work again!

I think there is a mechanical sensor inside the sound output (plug for the earphone) so that once it senses a plug getting in, it shuts internal speaker.

Maybe the mechanical sensor was jammed (spring problem i guess) and it still believe that u have ur earphones plugged-in. "Clogging" the hole for the earphones would allow the spring to spring back to initial position...

Hope it helps
